Vintage 1970s Ti Cat helmets

Hi there
Looking for a resource or anyone who may know something about vintage Ti Cat helmets. Particularly if there was ever a time in the 1970s where they only had the leaping Tiger logo on one side of the helmet?
Thanks

Never happened.

The only team I can think of that even has the logo on one side is the Steelers.

The Ticats alternate uniform from a couple years ago had the logo on just one side, and the player’s number on the other side of the helmet. It certainly didn’t happen in the 70’s though.

Thanks for replies.
Basically confirmed what I figured as well.
